I am considered to be an early adopter by most of my peers, but there are some things that I will never be able to adopt, not even late, however much environmentally minded I may be. Why? I am afraid this thing just looks about as ridiculous as grown up people on scooters. I've been playing with pushcarts when I was five, I think. Granted, they were less technologically savvy, but still. I think you need to be a bit retrogressively biased to play with one of these. Sorry if I am insulting anyone. And then you are not protected against the elements on one of those things, nor do you do anything for your physical fitness.
